FAQ

What is the maximum operating frequency and associated DMIPS rating for the R5F100ECANA#U0?

The R5F100ECANA#U0 operates at up to 32 MHz with a performance rating of 41 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and −20°C to +85°C. The RL78 CPU core's 3-stage pipeline and efficient CISC instruction set enable this throughput while maintaining ultra-low power consumption - critical for real-time control in energy-constrained systems.

Does the R5F100ECANA#U0 support background data flash rewriting while executing application code?

Yes, the R5F100ECANA#U0 supports Background Operation (BGO) for data flash. While the 4 KB data flash is being rewritten, the CPU can continue executing instructions from program memory without interruption. This capability is essential for applications requiring continuous operation during firmware updates or secure data logging - and is implemented in hardware without software polling or interrupt overhead.

What are the key low-power modes supported by the R5F100ECANA#U0, and what is the lowest achievable current draw?

The R5F100ECANA#U0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - verified at VDD = 1.8–5.5 V and TA = −40°C to +85°C. This enables multi-year battery life in always-on sensor endpoints, and the RTC retains calendar functionality and alarm capability without external components.

Can the R5F100ECANA#U0 be used in LIN bus networks, and which peripheral handles LIN protocol compliance?

Yes, the R5F100ECANA#U0 supports LIN 2.2 through its UART peripheral, which includes hardware features such as automatic sync-field detection, break generation/detection, and checksum calculation. No external LIN transceiver is required for physical layer interfacing - only a standard LIN transceiver IC (e.g., TJA1020) is needed to drive the bus. This integration reduces BOM count and simplifies compliance in automotive body control modules.

What is the ADC resolution, channel count, and special analog features included in the R5F100ECANA#U0?

The R5F100ECANA#U0 integrates a 10-bit successive-approximation ADC with up to 26 input channels. It includes dedicated AVREFP/AVREFM pins for precise ratiometric measurement, an internal 1.45 V reference voltage source, and an integrated temperature sensor - all accessible without external components. These features enable accurate sensor signal acquisition in industrial and consumer applications where calibration stability and board space are critical.
